This patch enhances that behavior to provide > option not to create fallback tunnels in root-ns as well. Since modules > that create fallback tunnels could be built-in and setting the sysctl > value after booting is pointless, so added a kernel cmdline options to > change this default. The default setting is preseved for backward > compatibility. The kernel command line option of fb_tunnels=initns will > set the sysctl value to 1 and will create fallback tunnels only in initns > while kernel cmdline fb_tunnels=none will set the sysctl value to 2 and > fallback tunnels are skipped in every netns. > > Signed-off-by: Mahesh Bandewar <maheshb@...gle.com> Applied to net-next, thank you.
